How to Use this Coin Size Comparison Generator

The tool is actually quite easy to use. You just need to choose a coin from the dropdown list and add it to the chart for size comparison. With respect to removing any figure, you can achieve that under the ‘Remove’ tab.

Please note also you can modify the position of any figure on the chart by dragging.

It’s worth noting there is a maximum number of four figures that can be added to the chart. This limit excludes the man’s hand which can be used for size reference if needed. Of course, you can always remove existing figures if you reach the limit and want to add new ones.

In order to get the best visual results for comparing the sizes of US coins, try to do the following:

  • When using a mobile device, make the view horizontal (i.e. landscape orientation)
  • Access the tool from a computer or large tablet if at all possible

It’s worth mentioning the coin sizes range from 14 mm (slightly over half an inch) all the way to over 76 mm (almost three inches).

Please keep in mind that for UK, Canada, Australia, and New Zealand; we only included coins that are copyright-free in order to avoid any legal issues. This basically means adding only old coins for those four countries.

Also, to ensure it’s clear which coin belongs to what country; we added the country code in the coin’s name between brackets if it’s needed. The countries where no code was included are the United States, Japan (yen), Russia (kopek and ruble), and eurozone (euro and euro cent).

Conclusion

Whatever coins you want to compare the size between, this accurate online tool will help you out. You just need to add the desired coin to the chart along with the hand in case you want a size reference.

It’s worth mentioning the chart axis shows the length measurement in both metric (i.e. millimeters) and imperial units (i.e. inches or thou). So, you won’t need to worry about unit conversion.

We hope this generator will help you out in visualizing the real difference between coin sizes within several countries including the United States and United Kingdom.
